of the axis of the guideway a distance equal to the length of the groove by any well known means (suchas the connecting rods shown) of producing reciprocating move ment from the continuous rotation of a shaft L and so arranged that the phase of the reciprocating motion f eaohrod differs by ap )roXimately 180 degrees from that of the ot er, thus causing the two rods "A A to move in opposite directions.

'Moiinted'on the same shaft as that pro ducing the movement of the rods is a cam M, "Figs, 1 and 2, which, by means of a roller N and a system of rods() and levers operates the switches at the required moment in the duration of the movement of the rods so that'the rollers C on the rods are deflected from 'onegroove to the other and produce the lateral displacement of the rods as before described. i

In this'manner the rods as they reciprocate alternately move one stroke in the direction of the way of the desired movement of the a, body or' bodies during which their projectionsor fingers are engaged with it or them, and one stroke in thereverse direction during which the projections or fingers are dis engaged or vice ver'sa.

The position of the projections or fingers on either rod is suchnm when one rod has completed its stroke'in? either direction and the lateral movement commences the projections or fingers of the other rod comname their lateral movement in the opposite direction-so that if the former commence to be disengaged from the body or V bodies the latter simultaneously commence to engage it 'or them or vice versa, such action precluding the possibilityof the body orjbodies slipping back or falling in the giiidewa a It wil be observed that when the hoist is vertical or inclined mere reversal ofthe driving mechanism causes it to"reverse the direction of its actionthat is to lower bodies under the action of gravity instead offfraise them.

2. In a mechanism of the character desired, a plurality of rods having projecting fingers and followers, cam tracks for each rod, engaged by said followers, said tracks being mainly parallel with the longitudinal direction of the respective rod and merging into one another at spaced points, means for imparting to the rods reciprocatory movements differing in phase from one another parallel with the and means for transferring the followers from one track to another.
